I got mighty confused when I first started laying out the cells and for a while thought it was not going to be possible to make 7 cells wide fit...then I refereed back to Allex's layout pic and realised I was positioning it all wrong. The ONLY way to fit 7 cells within the 120mm width of the Fighter frame is if they are staggered. It makes sense now that I can see it, but it does make it tricky to assemble. I happen to have a napkin holder that is the perfect width for 2 staggered rows which I already used to construct the long battery I used in my recumbent commuter. Keeping everything aligned and straight is harder than you would think making one of these things, but it will definitely be worth it in the end.

I 'think' I might be able to claim worlds longest range Fighter once this is done.

Hello
I recently purchased a bomber b52 (second hand) with 44 battery cycles and am having problems with it charging. I rode it once and charged it fine to 100% but after this morning's quick ride, it won't charge. The charger seems to start charging but then changes to red and green within 10mins or so. Has anyone else had this problem??
Thanks

I was going to say, damn losing an extra few lb you look just like JK now!
Was this photo taken with a potato to protect his identity ?

Yah no shit. It was taken with my crappy 1mxp flip phone camera. But don't worry, I jut ordered a new phone, its not a smart phone either. Infact its even older school than the flip phone, its a phone with the key pad on the outside, doesn't even flip.

Almost ready to start welding this monster....just one more series module to make for the top, then the spot welding can commence.

It occurred to me the other day that once this 2.5KWhr pack is done, I will have the worlds largest capacity, longest range Fighter.
This is something I have dreamed of doing since I first bought my Fighter way back in 2011. 200km range is not something I will easily be able to have a problem with any time soon.

Battery pack Envy... must be a few of us needing new packs by now. DIY option isn't possible for some of us, therefore bomber owners that bought new batteries please post up.
Where purchased?
What type of chemistry?
What cells?
What configuration?
Did you have to upgrade controller?
Amount of amps ..volts?
Need battery.. I've been commuting on my trusty old A2B Metro. Which sucks cuz I have to also use the train. On the bomber no train all 42 MI round trip traffic cutter.

Thought I'd throw this out there. Any stealth owners with battery building skills need a South Florida vacation?
Barter trade your skills for a couple of weeks in the Sun.
I'm half mile from Ocean.
Have other electric bikes to use. kayaks, surfboards,
BMX bikes with track 15 minutes away
Wife kid all welcome.

Yeah, the DIY option certainly does require some skill and a whole lot of patience. It's taken me years of tinkering and learning to reach the point I'm at now with the confidence to do this. My build is coming along nicely btw. Although I probably only need 2 layers, I'm going with 3 layers of 0.15x7mm nickel to give the lowest possible resistance across the series links.

If someone is really keen I would be willing to consider making a pack like this for anyone based in Australia as I have all the tools/knowledge now. It would not be cheap, but would probably not be much more than a new stock Stealth pack, and gives double the capacity of a stock pack.

Wow what a good offer! I'd love it .... I'm on the other side of the pond but I live as close as you to the Mediterranean sea
In the next months I'll be building my own new Bomber battery and I'll use copper strips (0.2mm x 8-10mm?? TBD) for series connections with (as short as possible) nickel strip 0.2mmX10mm spot welded to the battery terminals. The battery will be 20S14P made of Samsung 30Q.

Reset it again and charge it up. What I think is going on is the battery maybe starting to get old, and when you whack the throttle, you end up bouncing off the BMS causing the shutdown. If this is the case, the two best solution are to turn down the current a little. If you have the DC1, bring the current down to 4500w, if you have the CA, bring your amps down to 50 or so. This should resolve the issue.

Email stealth about new battery pack. They said I will have to send them controller for upgrades to be able to utilize the regen braking. What are the upgrades? Is it worth upgrading or should I just purchase new controller?
Which controller will work with ca3?

Hi,
i have a question. Which one is a better fork for the b52. The marzocchi 888 (2014) or the new dnm fork that stealth uses. I m getting a new b52 and thinking to swap my old bomber's 888 fork and install it to the new b52.

In addition to what EMX Trials said, I have ridden both the 2014 Zocks and the DNM Forks that Stealth uses. In stock trim, the DNM is a better fork. That said, if you want to send the Zock fork to a suspension specialist, it will come back to you better than a DNM. The stock Zocks, specifically the 888CR fork, has some serious stantion tube stiction issues, I don't know why that is.
